7，总结：

开始配置proxy_store /app/$host${uri}时在/app目录下总是无法生成$host目录www.b2b.cn，经检查error.log发现/usr/local/nginx/proxy_temp目录没有权限，删了proxy_temp目录，重新启动killall -s HUP nginx后还不行，后来发现应该将下面配置文件放在最后面：（开始时在server下）

location ~ / {

expires 1d;

proxy_pass http://www_b2b_cn_backend;

proxy_set_header Host $host;

proxy_set_header X-Forwarded-For $remote_addr;
